However, none of these restrictions make a source program written for FOR TRANSIT incompatible with the FORTRAN system for the 704.

The KSR systems ran a specially customized version of the OSF / 1 operating system, a Unix variant, with programs compiled by a KSR-specific port of the Greenhills C and FORTRAN compilers.

Toward the end of the PDP-8 era, operating systems such as OS / 8 and COS-310 allowed a traditional line mode editor and command-line compiler development system using languages such as PAL-III assembly language, FORTRAN, BASIC, and DIBOL.

Unlike other process VMs, these systems do not provide a specific programming language, but are embedded in an existing language ; typically such a system provides bindings for several languages ( e. g., C and FORTRAN ).

I was writing in MAD, which was much easier and more pleasant than the FORTRAN and COBOL that I had written earlier, and I was using CTSS, the first time-sharing system, which was infinitely easier and more pleasant than punch cards.

Because a number of people were interested in using the FORTRAN language and yet wanted to obtain the speed of the MAD compiler, a system called MADTRAN ( written in MAD ) was developed.

IBSYS was a " heavy duty " production operating system with numerous subsystem and language support options, among them FORTRAN, COBOL, SORT / MERGE, the MAP assembler, and others.

FMS, the Fortran Monitor System, was a more lightweight but still very effective system optimized for batch FORTRAN and assembler programming.

Originally the software, including an operating system and a FORTRAN compiler, were done under contract by Computer Usage Company, under direction of George R. Trimble, Jr.

The system nucleus ( kernel ) was written in IBM / 370 assembler but most of the native applications were written in FORTRAN.

The FORTRAN Assembly Program ( FAP ) was an assembler for the 709, 7090, and 7094 under IBM's makeshift FMS ( Fortran Monitor System ) operating system.

The commands were often believed to be part of the BASIC language by users, but, in fact, were part of the time sharing system and were also used when preparing ALGOL or FORTRAN programs via the DTSS terminals.

This was until a manager at Tymnet wrote a small FORTRAN IV program to maintain a list of problem reports and track their status in a System 1022 database ( a hierarchical database system for TOPS-10 published by Software House ).

The HP 2116A ’ s software, with a FORTRAN compiler, assembler, linker, loader, operating system, and I / O drivers were ready at the same time as the hardware.

A minimum system would leave just over 10KB of storage available for a single batch partition which was enough to run utilities and all compilers but COBOL and full FORTRAN IV.

These commands were often believed to be part of the Dartmouth BASIC language by users but in fact they were part of the time sharing system and were also used when preparing ALGOL or FORTRAN programs via the DTSS terminals.

* System software including a disk operating system and FORTRAN, BASIC and Assembly languages.

VOS provides compilers for PL / I, COBOL, Pascal, FORTRAN, VOS C, BASIC, and C ++.. Each of these programming languages can make VOS system calls ( e. g. to read a record from a file ), and has extensions to support varying-length strings in PL / I style.

The Kronos software included: several versions of the proprietary operating system Excelsior ; the Modula-2, C, and FORTRAN compilers ; several CAD systems, and several other applications.

He lobbied UIUC to adopt the 1968 WATFOR one-pass FORTRAN compiler / runtime system from the University of Waterloo in Ontario.

Some sources have said that the Laning and Zierler system was the inspiration for FORTRAN.

It was designed to avoid some of the perceived problems with FORTRAN for backward compatibility with historic Buran ( spacecraft ) ALGOL software.

The language was based on FORTRAN II, with some influences from ALGOL 60 and with additions to make it suitable for timesharing.

His " Software Tools " series spread the essence of ' C / Unix thinking ' with makeovers for BASIC, FORTRAN, and Pascal-and most notably his ' Ratfor ' ( rational FORTRAN ) was put in the public domain.

The names of earlier versions of the language through FORTRAN 77 were conventionally spelled in all-caps ( FORTRAN 77 was the version in which the use of lowercase letters in keywords was strictly nonstandard ).

Because the capitalization was never completely consistent in actual usage, this article adopts the convention of using the all-caps FORTRAN in referring to versions of FORTRAN through FORTRAN 77 and the title-caps Fortran in referring to versions of Fortran from Fortran 90 onward.

" FOR TRANSIT " was the name of a reduced version of the IBM 704 FORTRAN language,

During the same Fortran Standards Committee meeting at which the name " FORTRAN 77 " was chosen, a technical proposal was incorporated into the official distribution, bearing the title, " Letter O considered harmful ".

During the standards committee battle over whether the " minimum trip count " for the FORTRAN 77 < CODE > DO </ CODE > statement should be zero ( allowing no execution of the block ) or one ( the " plunge-ahead " < CODE > DO </ CODE >), another facetious alternative was proposed ( by Loren Meissner ) to have the minimum trip be two — since there is no need for a loop if it is only executed once.

Zork was ported under the filename " DUNGEN ", dungeon, to FORTRAN by a programmer working at DEC in 1978.

Later in the 1950s, assembly language programming, which had evolved to include the use of macro instructions, was followed by the development of " third generation " programming languages ( 3GL ), such as FORTRAN, LISP, and COBOL.

* PL / I ( NPL ) was designed in the early 1960s to incorporate the best ideas from FORTRAN and COBOL.

The FORTRAN version was also included in the distribution media for some Data General operating systems.

The first important computer programming language to use the equals sign was the original version of Fortran, FORTRAN I, designed in 1954 and implemented in 1957.

Other instructions were designed to support the internal data structures and operations of programming languages such as FORTRAN, COBOL, and PL / I.

A module is a collection of FORTRAN subroutines designed to perform a specific task — processing model geometry, assembling matrices, applying constraints, solving matrix problems, calculating output quantities, conversing with the database, printing the solution, and so on.

The earliest high-level programming languages, including FORTRAN ( 1957 ), COBOL ( 1960 ), and ALGOL 60 ( 1960 ), had support for multi-dimensional arrays, and so has C ( 1972 ).

Taking advantage of this feature, some languages ( like FORTRAN 77 ) specify that array indices begin at 1, as in mathematical tradition ; while other languages ( like Fortran 90, Pascal and Algol ) let the user choose the minimum value for each index.

* FORTRAN H, a Fortran implementation for the IBM System / 360 and System / 370 mainframes

The first manual for FORTRAN appeared in October 1956, with the first FORTRAN compiler delivered in April 1957.

Ratfor and Ratfiv, for example, implemented a C-like language, outputting preprocessed code in standard FORTRAN 66.

* Online FORTRAN compiler for small experiments

* April – IBM sells the first compiler for the FORTRAN scientific programming language.

It may have been derived from the earlier principle of using the first letter of a variable name to set its type — for example, variables whose names started with letters I through N in FORTRAN are integers by default.

Ken Williams, a programmer for IBM, bought an Apple II microcomputer with which he planned to use to develop a FORTRAN compiler for the Apple II.

The programming languages FORTRAN and LISP were first developed for the 704, as was MUSIC, the first computer music program by Max Mathews.

* 1993: John Backus for his development of FORTRAN, the first widely used, general purpose, high-level computer language.
